Movable closed shutter unloading device

Abstract

The invention discloses a movable closed shutter unloading device, which is designed to solve the problems of the existing device that the effect is poor, the operation cost is high and the like. The movable closed shutter unloading device provided by the invention comprises a framework, a movable unloading vehicle, a first pulling sheet, a second pulling sheet, a movable shutter and a transmission unit. The transmission unit comprises a shaft seat, a transmission ratchet wheel, a transmission shaft, and a positioning unit composed of a spring and a movable pin. The transmission shaft is connected with the movable shutter through a cam structure and is used for controlling the opening and the closing the movable shutter; or the transmission shaft is serially arranged in the movable shutter, and the transmission shaft is matched with the movable shutter in an interference fit manner; or the transmission shaft is fixedly arranged on the movable shutter. The movable closed shutter unloading device provided by the invention is applicable to all movable unloading occasions, and has the advantages of good sealing effect, close match with a process, reasonable structure, long service life, low operation cost and stable whole work performance.

Description

technical field [0001] The invention relates to a movable airtight louver unloading device. Background technique [0002] At present, when the mobile unloading vehicle is unloading at a fixed point, adhesive tape is generally used to partially seal the material slot. When moving the unloading truck to unload, the sealing tape at the unloading place is propped up by the guide roller on the unloading chute, so as to unload to the chute. [0003] The sealing method of the tape is passively applicable to the requirements of the unloading process, and the sealing effect is not good, and the dust spillage is serious. In addition, because the tape is generally made of rubber, after long-term operation, the seal is not tight due to severe wear and tear, and the sealing tape needs to be replaced frequently, resulting in high operating costs. Contents of the invention [0004] In order to overcome the above-mentioned defects, the present invention provides a movable airtight louve...
